Radio is the first wireless mobile communication equipment used by human beings, as early as the 1930s began to be used. After nearly a century of development, the application of the walkie-talkie has become very common, from specialized fields to ordinary consumption, and from military to civilian use. So, the question arises, no matter how the walkie-talkie looks different, but in terms of color...
In the impression of many people, the walkie-talkie is generally the image of "stupid, black and rough", and our requirements for it are often reliable and durable.

We know that the antenna of the intercom is proportional to the transmission and reception of the walkie-talkie, and the antenna is a device that emits electromagnetic waves into the air. We usually use walkie-talkies in order to send more power into the air, so that when the other party receives the signal, there is still enough power to restore the content of the information. The antenna is an i...
In the outdoors, walkie-talkies are in some cases more useful than mobile phones, as they do not require external base station support and can communicate freely with teammates in most harsh environments. In times of disaster, a GPS-enabled walkie-talkie can be used to send SOS signal. The theoretical frequency band of Frs walkie-talkies is in the range of 144-146 and 430-440MHz. In fact, the cent...
Everyone knows the importance of UHF/VHF bands height to communication distance and effect. On the top of the mountain, it is possible to communicate with quite distant stations with only common handheld radio. However, we cannot stay on top of the mountain all the time. If there is a device that can help us transmit signals at a high place, then we can make full use of the advantage of heig...
First of all,make it clear that we can carry walkie-talkies on a plane. However, when we go through airport security, we need to cooperate with the security officer by switching off the walkie-talkie and removing the battery from the radio and carrying it separately from the main unit. It is also important to note that the walkie-talkie cannot be switched on and used on the aircraft. The aviation ...
